NUT-LOCK.

Original application filed November 17, 1915, Serial No. 61-,963.

Serial No. 68,023.

To all whom it may concern Be it known that I, EUGENE F. LOWE, a citizenof the United States, residing at Delevan, in the. county of Gattaraugusand State of New York, have invented certain new and useful Improvmentsin Nut-Locks, of which the following is a specification,

drawings.

My invention relates to means for preventing the accidental unscrewingof nuts or bolts, and particularly to a means peculiarly designed foruse in connection with the rail chairs such as are shown in my iendingapplication for patent Serial No. 61,963, filed November 17, 1915, onrail chair and joint, of which application this present application is adivision.

The general object of my invention is the provision of means which willprevent the accidental unscrewing of nuts on those bolts which formprimary fastenings for rail chairs, this means, however, permitting theready removal and replacement of the nut or nuts whenever desired.

Still another object of the invention is to provide a nut locking orholding means of such form that vibration incident to the travel oftrains over rails will not cause the nut holding or locking means toshift from its operative engagement with the nut or nuts.

Another object is to provide means of this character which shall be verysimple, easily manipulated, easily applied, and very effective inaction.

invention is illustrated in the accom-' panying drawings, wherein:

Figure 1 is an elevation, partly in section, of a portion of a tiehaving a rail chair provided with my improved nut locking devices; Fig.2 is a section on the line 2- -2 of Fig. 1.

Referring to these drawings, 13 designates a rail and A a tie upon whichthe rail is mounted. As illustrated, the rail B is mounted in a chair10having under-cut endflanges, and rail-engaging members 11 are disposedbetween these end flanges and the rail and engage over the base of therail. These rail-engaging members 11 as illustrated are each formed witha longitudinally" extending recess 12 having a flat upper face, therail-engaging members and the chair being bored for the passage ofvertically dis- Specification of Letters Patent.

Patented Nov. 14, 1916.

Divided and. this application filed December posed bolts 13 which passthrough the tie and operatively engage therewith. The bolts are screwthreaded at their upper ends for the reception of nuts 11, andthe'object of the present invention is to provide means for holdingthese nuts in place.

To this end the side wall 15 of the recess 12 is formed at spacedintervals with inwardly extending bores 16 and disposed in each bore isa coiled spring 17 which bears outward on a locking head 18. This headis shouldered at its middle to provide a portion embraced by the end ofthe springs and a stud which is engageable with an opening formed in atransversely extending strip 19. This strip 19 has a length equal tothat of the corresponding rail engaging member 11, and this strip, itwill be seen, is resiliently urged outward at its opposite ends andagainst the flat side faces of the nuts 1%. After the nuts have beenturned down to engage the work, the heads 18 will. be forced inward byany suitable means, as by an implement fitted for the pu pose, and thestrip 19 dropped into place between the faces of the nuts and the faceof the recess 12. The strip 19 is formed with perfora tions 20 intowhich the studs on the heads 18 are adapted to engage as illustrated inthe drawing so that when the strip 19 is forced into place the studs onthe heads 18 will automatically spring into these perforations 20 assoon as the strip has reached its proper position, thus locking thestrip 19 in place and preventing any'movement of the strip until theheads 18 have been forced rearward. When it is desired to release eitherpair of nuts 15, the locking heads 18 are forced inward by any suitablemeans, as for instance, a nail, and the strip withdrawn. This permitsthe nuts to be turned in a reverse direction.

While I have illustrated my invention as applied to a particular form ofrail-engaging member, and while it is peculiarly adapted to theconditions of railway service, yet I do not wish to be limited to thisapplication as it is obvious that other locking devices of the samecharacter and operating on the same principle may be used in a largevariety of circumstances. One reason why my improved device ispeculiarly adapted for railway service is that the vibration caused bypassing trains will not affect the locking heads 18 because of thecushioning effect of the springs 17. These springs, furthermore, alwaysforce the plate 20 against the nuts 14L. Furthermore, inasmuch as thisplate 20 has preferably a thickness equal to the distance between theflat face of the nut and the face of the recess 12, it is obvious thatthe nut cannot possibly become unscrewed.

It will be seen that the means for holding the stri p 19 in place is toa large extent concealed so that there is no surface offered tomischievously inclined persons to remove the locking device.Furthermore, it is very readily possible to so form the perforations 20in the strip 19 that a peculiarly formed implement would have to be usedin order to be inserted through the strip and engage the heads 18;

Having described my invention, what I claim is:

1. The combination with a body having a bolt perforation, saidext-ending parallel to the bolt perforation and spaced therefrom. a boltpassing through said perforation, a nut mounted on the bolt, a memberdisposed between a side of the nut and the adjacent face of the body andpreventing rotation of the nut, and a resiliently actuated memberoperatively engaging the nut-locking member and holding it in place, the'bodyhaving a recesswithin which said resiliently actuated member ispositively housed.

2. The combination with a body having a bolt perforation, said bodyhaving aface extending pa fallel to the bolt perforation and spacedtherefrom, a bolt passing through said perforation, a nut mounted on thebolt, a member disposed between the side of the nut and the adjacentface of the body and preventing rotation of the nut, and means forholding said member in place, said means including a resilientlyactuated locking stud mounted upon the body and engaging with theperforations in the plate.

Copies of this patent may be obtained for five cents said body theperforation. in said member to lock 1t body having a face 3. Thecombination with a body having a bolt perforation and formed with a faceextending parallel to the perforation and with bores extending inwardfrom said face, of a bolt passing through the perforation and having anut, a member disposed between the nut and the said face of the body andpreventing the rotation of the nut when in place, said member having arecess upon its inner face, a spring disposed in each bore, and alocking stud outwardly urged by the spring and adapted to engage in thecorre sponding perforation of said member.

4. Thecombination with a nut and bolt, of a body having a face disposedparallel to a side of the nut, a perforated member disposed between thenut and said face and preventing the rotation of the nut, and anoutwardly urged locking stud mounted upon and adapted to be projectedinto in place.

The combination with a body having a bolt perforation formed with a wallhav ing a face extending parallel to the axis of the perforation, of abolt passing through the perforation, and a nut therein having its sideface disposed opposite said wall, a member removably disposed betweenthe face of the nut and the face of the wall and preventing the rotationof the nut, said member being perforated at a plurality of points, thewall being-formed with a plurality of bores, coiled springs disposed inthe bores and heads mounted upon said coiled springs and having studssmaller than the heads and, adapted to be received in said perforationsand lock the member in place. 7 In testimony whereof I hereunto atfix mysignature in the presence of two witnesses.
